This video demonstrates a Florida sleeve valve-sparing aortic root repair, repair of the leaking bicuspid valve with raphe shaving, virtual basal ring annuloplasty and leaflet plication, and ascending through proximal arch replacement with alternate aortic cannulation/clamping.

Patients entered into a clinical trial of TAVR and patients in two registries were evaluated for possible subclinical leaflet thrombosis in their bioprosthetic valves. 40% of the patients in the TAVR trial and 13% of registry patients were found to have such thrombosis. The risk was lower in patients anticoagulated with warfarin. Therpeutic antico

In an interview filmed at the 2015 STS Annual Meeting in San Diego, California, Tom Nguyen speaks with Michael Reardon, Chief of Cardiac Surgery at the Methodist DeBakey Heart & Vascular Center in Houston, TX.

The authors conducted a propensity-matched analysis of outcomes and costs associated with TAVR vs. SAVR procedures in patients considered either intermediate risk (STS PROM 4-8%) or high risk (STS PROM >8%) within the Commonwealth of Virginia.

This study describes activity and outcomes for both standard aortic valve implantation and transcatheter aortic valve implantation (TAVI) in England and Wales in the TAVI era. The study demonstrates that both standard aortic valve implantation and TAVI acitivity have increased since TAVI was first performed in the United Kingdom.

This video describes how to perform a minimally invasive aortic valve replacement via a right mini thoracotomy approach.
Comparative Histology of Aortic Dilatation Associated With Bileaflet Versus Trileaflet Aortic Valves
September 9, 2015
Resected aortas associated with a bicuspid aortic valve (BAV,n = 60) and trileaflet aortic valve (n = 24) in patients with aortic valve disease were compared with normal diameter aortas from patients undergoing cardiac transplantation (n = 16) by five histologic criteria.

Short- and mid-term outcomes of TAVR for nonagenarian (>90 years) patients in the PARTNER-1 trial were assessed for 531 pts. MACE occurred in 35% including stroke in 3.6%. Important paravalvular leak occurred in 1.4%. 30-day mortality was 4% and 3-year mortality was 48%, which compared to 44% in a matched population. QOL stabilized at 6 months

The authors of this study compared quality of life in patients at increased surgical risk who underwent either transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR).
